You can draw calligraphic lines with Designer by selecting both Thick and Calligraphic on the Line Thickness page of the Object Format dialog box. Then you change the pen width, height, and angle settings. Calligraphic lines can add a more natural look to many drawings, especially when used with curved lines.
The primary way to set calligraphic lines is to adjust the width and height settings. The lines with the most flair are produced by choosing very different width and height settings. For example, a very thin but very tall setting will produce a calligraphic line even without adjusting the pen angle setting.
Adjusting the pen angle setting can enhance the effects created with the width and height settings. In a calligraphic line, the pen angle setting forces the pen tip to stay at the chosen angle, much as a calligraphic pen is held at particular angles to achieve certain effects.
